ADRV

Right ADC Channel Output Valid Flag. Set to “1” if slot 3 (or 19) contains valid right ADC capture data.

ADLV

Left ADC Channel Output Valid Flag. Set to “1” if slot 2 (or 18) contains valid left ADC capture data.

DA2RQ

DAC2 Input Request Flag. Set to “1” if DAC2 is enabled and its four word stereo input buffer is not full.

DA1RQ

DAC1 Input Request Flag. Set to “1” if DAC1 is enabled and its four word stereo input buffer is not full.

res

Reserved for future expansion. Read back as “0.” Should be ignored to ensure future compatibility.
